IEEE 656-1992

IEEE 656-1992 is the standard for measuring audible noise from overhead transmission lines, giving utilities and engineers a defined way to assess sound levels associated with high-voltage power systems. In the power, energy and industry applications space, this matters because noise evaluation can influence line design, environmental review, and public acceptance. IEEE 656-1992 helps create a more consistent basis for comparing measurements and interpreting results for transmission-line projects.

About IEEE 656-1992

This technical document focuses on how audible noise from overhead transmission lines should be measured, rather than on the design of the lines themselves. IEEE 656-1992 is relevant wherever transmission-line noise needs to be characterized in a repeatable way, especially for engineering studies and compliance-related review. By defining a measurement approach, it supports more consistent results across locations, operating conditions, and reporting practices. For buyers working with line-performance documentation, it provides a clear reference point.

Where is IEEE 656-1992 used?

IEEE 656-1992 is commonly used in transmission planning, field measurement programs, and environmental assessments tied to overhead power lines. It is especially relevant when engineers need to evaluate audible noise near rights-of-way, substations connected to transmission corridors, or other high-voltage infrastructure. The standard can also support utility studies, consultant reports, and procurement specifications where noise performance must be documented with a recognized method. Its focus is practical measurement in real operating conditions.

Importance in practice

In practice, IEEE 656-1992 helps reduce ambiguity when audible noise measurements are needed for overhead transmission lines. A shared measurement basis can support better design decisions, clearer documentation, and more defensible comparisons between projects or operating scenarios. It may also assist with stakeholder communication, since consistent data is easier to review and verify. For organizations managing power-line performance or public-impact concerns, IEEE 656-1992 offers a useful reference for control, consistency, and risk reduction.
